It actually is rather easy:
When you download the files from Project Gutenberg, I assume you do so from a page such as the following:
I simply cut and pasted the bibliographic record in my previous message from that page.
Here is another example of a text from the Harvard Classics series located at PG:
Bibliographic Record [help] Creator Jean Froissart, Thomas Malory, Raphael Holinshed
Title Chronicle and Romance (The Harvard Classics Series)
Release Date 2004-10-08
Copyright Status Not copyrighted in the United States. If you live elsewhere check the laws of your country before downloading this ebook.
Note that the title is "Chronicle and Romance (The Harvard Classics Series)" In titling the work for your project, you could simply use "Chronicle and Romance," noting that it came from the Harvard Classic Series below the title or on a subsequent page. The authors, likewise, should be "Jean Froissart, Thomas Malory, Raphael Holinshed," not Harvard Classics. Indeed, I would think it best to break out each work from that volume as separate works, giving each of them their own titles and authors.
As to the LC record, you can simple visit http://catalog.loc.gov/
, do a search for the edition you are working on, and copy and paste the bibliographic record into your ebook.
Another advantage of doing some of this is that perhaps you can induce a much wider group of editors to create the etexts. Your tutorial is excellent. If you can get some librarians interested, they'll have the 20,000+ volumes in the PG collection completed in a year or two, if not sooner. This is what we do for a living. Many of us have graduate degrees in this.
Alternatively, with the editors' permission, librarians might be induced to add the bibliographic records to the otherwise completed works before final submission.
Your efforts are magnificent. I would just like to see your final product obtain a much wider recognition and use. Why limit your work product to those who, like me, happen upon them in an effort to discover what free content is available to the Sony Reader? This should be in library catalogs everywhere. (By the way, the individual e-editor or e-editors of each work should also include that in the editions they create. E.g., "Sony Reader version created by HarryT from the etext available at Project Gutenberg . . . ."
Once a format was settled on, doing all this would not add more than five minutes to creating each work.
